Download USE OF A STOCHASTIC MODEL TO EVALUATE UNCERTAINTY IN A PERFORMANCE ASSESSMENT AT THE SAVANNAH RIVER SITE - 8120 Book in PDF, ePub and Kindle
A significant effort has recently been initiated to address probabilistic issues within radiological Performance Assessments (PA's) conducted at the Savannah River Site (SRS). This effort is considered to be part of a continual process, as is the program of PA analysis and maintenance across the Department of Energy (DOE) complex. At SRS, findings in the initial probabilistic analysis of the Slit Trenches in the E-Area PA were built upon and improved in the later development of the probabilistic model for the F-Area Tank Farm. Within the PA studies conducted at SRS, the initial effort of the uncertainty analyses was focused on the Slit Trenches as part of the E-Area PA. Specifically, a probabilistic model was developed for Slit Trench 5 within the E-Area. This model was utilized in deterministic mode to compare its results against the 2- and 3-D model results of the deterministic models. Then, utilizing the PDFs, the model was used to perform multiple realizations and produce probabilistic results. Later, a second probabilistic sensitivity and uncertainty analysis was undertaken for the F-Area Tank Farm PA. This effort is currently underway. Many improvements were made in how the flow and transport processes were incorporated within this model.

Download Development of Probabilistic Uncertainty Analysis Methodology for SRS Performance Assessments Maintenance Plan Activities Book in PDF, ePub and Kindle
An initial uncertainty analysis of the Performance Assessment (PA) model of the Savannah River Site (SRS) trench disposal unit was conducted. Selected input data values were varied for both flow and transport analyses to generate input sets called realizations. Outputs of fluxes to the water table and well concentrations were compared to results from the PA. This stage of the uncertainty analysis served as a prototype for future work. The focus was to lay the foundation for a more comprehensive analysis, generate a limited set of output results, and learn about the process and potential problems.

Download Stochastic Analysis in Production Process and Ecology Under Uncertainty Book in PDF, ePub and Kindle
The monograph addresses a problem of stochastic analysis based on the uncertainty assessment by simulation and application of this method in ecology and steel industry under uncertainty. The first chapter defines the Monte Carlo (MC) method and random variables in stochastic models. Chapter two deals with the contamination transport in porous media. Stochastic approach for Municipal Solid Waste transit time contaminants modeling using MC simulation has been worked out. The third chapter describes the risk analysis of the waste to energy facility proposal for Konin city, including the financial aspects. Environmental impact assessment of the ArcelorMittal Steel Power Plant, in Kraków – in the chapter four – is given. Thus, four scenarios of the energy mix production processes were studied. Chapter five contains examples of using ecological Life Cycle Assessment (LCA) – a relatively new method of environmental impact assessment – which help in preparing pro-ecological strategy, and which can lead to reducing the amount of wastes produced in the ArcelorMittal Steel Plant production processes. Moreover, real input and output data of selected processes under uncertainty, mainly used in the LCA technique, have been examined. The last chapter of this monograph contains final summary. The log-normal probability distribution, widely used in risk analysis and environmental management, in order to develop a stochastic analysis of the LCA, as well as uniform distribution for stochastic approach of pollution transport in porous media has been proposed. The distributions employed in this monograph are assembled from site-specific data, data existing in the most current literature, and professional judgment.

Download Land-Use and Land-Cover Change Book in PDF, ePub and Kindle
This book presents recent estimates on the rate of change of major land classes. Aggregated globally, multiple impacts of local land changes are shown to significantly affect central aspects of Earth System functioning. The book offers innovative developments and applications in the fields of modeling and scenario construction. Conclusions are also drawn about the most pressing implications for the design of appropriate intervention policies.

Download Soil Carbon Book in PDF, ePub and Kindle
Few topics cut across the soil science discipline wider than research on soil carbon. This book contains 48 chapters that focus on novel and exciting aspects of soil carbon research from all over the world. It includes review papers by global leaders in soil carbon research, and the book ends with a list and discussion of global soil carbon research priorities. Chapters are loosely grouped in four sections: § Soil carbon in space and time § Soil carbon properties and processes § Soil use and carbon management § Soil carbon and the environment A wide variety of topics is included: soil carbon modelling, measurement, monitoring, microbial dynamics, soil carbon management and 12 chapters focus on national or regional soil carbon stock assessments. The book provides up-to-date information for researchers interested in soil carbon in relation to climate change and to researchers that are interested in soil carbon for the maintenance of soil quality and fertility. Papers in this book were presented at the IUSS Global Soil C Conference that was held at the University of Wisconsin-Madison, USA.

Download Manufacturing Processes for Technology Book in PDF, ePub and Kindle
For courses in Introduction to Manufacturing Processes in Engineering, Technology, Industrial Technology, and Manufacturing Technology programs. This practical text is devoted to the many ways in which raw materials are economically converted into useful products grouping together discussions of large-scale processes (materials addition, removal, and change), followed by coverage of applications. It allows students to build a thorough foundational knowledge of similarities and differences in processes, and to then understand how to choose the optimal processes for a specific project. Throughout the narrative, consideration is given to economies of time and material, to environmental consequences, and to the safety of various processes and procedures...as well as to presenting the most current, industry-sanctioned processes being used today.

Download System of Environmental-economic Accounting for Water Book in PDF, ePub and Kindle
The System of Environmental-Economic Accounting for Water, commonly referred to as SEEA-Water, is a conceptual framework for the organization of physical and economic information, developed with the purpose of providing an integrated conceptual framework to support water policy design and evaluation. It uses concepts, definitions and classifications coherent with those of the System of National Accounts. SEEA-Water is a subsystem of the System of Environmental-Economic Accounting (SEEA), which provides internationally agreed standards for the compilation of measures about the environment and its interactions with the economy. After a rigorous consultation process, SEEA-Water was adopted in 2007 by the United Nations Statistical Commission (UNSC). Part I of SEEA-Water has been adopted as an interim international statistical standard subject to re-evaluation when the SEEA is adopted as an international statistical standard.
